Seasonal Efficiency: New Energy Efficiency Label

Seasonal Efficiency: New Energy Efficiency LabelFrom January 2013, the energy performance calculation for air conditioning systems will change from an overall EU based standard of EER and COP to a new standard based on seasonal efficiencies of SEER and SCOP.

These changes to the Energy Related Products Directive or ErP are designed to give consumers a better understanding of the real efficiency of air conditioning and heat pump systems whose nominal power rating does not exceed 12 Kw. Undergoing gradual implementation from 1 January 2013 until 1 January 2019, the schedule for each product category is as follows:

Seasonal Energy Efficiency Ratio (SEER) – This is the overall energy efficiency ratio of the unit, representative of the entire cooling season. It is calculated as the annual cooling demand divided by the annual consumption of electricity for cooling.

Seasonal Coefficient of Performance (SCOP) - This is the overall coefficient of performance of the unit, representative of the entire heating season designated (the value of SCOP corresponds to a determined heating season).

It is calculated by dividing the reference annual heating demand by the annual consumption of electricity for heating.
